Does pressure washing rugs de-waterproof them?

[QueenDee_]

Thinking ahead to when rugs will need to be washed, if you use a jet/pressure washer to wash them does it remove the waterproofing?

In my experiance yes it does .

Yes to a certain extent. Might get away with it once but not regularly.

Not only removed the waterproofing but ripped a couple of rugs.
Its a very powerful pressure washer and I must have got carried away.
